I saw Ms. Gyse and Lillias White in Boston -- was completely blown away by both (and I had seen the show multiple times prior to the Boston tour stop).
FYI: "Julia McGirt" who now goes by the name, "Julia Nixon". I saw her play Effie and couldn't believe what I was I hearing, seeing and experiencing. She held notes for days, the end of "I Am Changing" was this incredible scooped note. I witnessed a forgotten, unappreciated miracle that no one will ever know about.
